Background:

Yangudi volcano, lying in the Addado graben of the northern Ethiopian rift, is a complex rhyolitic stratovolcano with an elliptical summit caldera. A trachytic lava flow originating in the caldera covers part of the southern flank of Yangudi, also known as Angudi, Jangudi, or Langudi. Rhyolitic obsidian domes on the NW flank are surrounded by younger basaltic lava flows. Very recent scoria cones and lava flows are located south of Yangudi along the eastern graben faults.---Smithsonian / GVP volcano information
